Try to remove the battery from the laptop and plug it directly on the power adapter. Many laptop have battery issue even on normal use and need to be replace ( battery). Then turn on the laptop and check for sound coming from the device . There should be a beep sound on start up. You could also try to connect an external monitor to check whether the monitor has a problem a busted inverter board on the LCD circuit could turn off the back light on the LCD. You could check this by turning off the lights and shine a bright light on the LCD and check for images. After doing this and you still cannot identify the problem on your laptop then it` high time to take the laptop to a professional computer tech to have it fix.

These are the ways to diagnose the problem in your laptop charging problem.

* First remove the battery and connect the AC charger connection. To check the laptop if its still working fine.
* The battery has already damage, it needs to replaced. * If possible you can try using other battery that fits and working on your laptop. * Then diagnose if the lights will still switch off. * If these option did not fix the problem. It has a technical problem inside.

Your Laptop may not have shut down properly and while you tried switching it on and due to fast access of the keyboard the screen may be blank or the red light instead of green. You can leave it for untill the red light also turn off that is battery totally to get over. Then charge and switch to the user mode.

The orange light located on the front of the Toshiba laptop turns orange when you are charging your laptop and goes back to green once the laptop is fully charged and goes out once you have unplugged it from the power supply.

Hello there! Red light means your "battery is low" and green light means "normal" but i don`t know what white color means. But as long as your laptop is working fine then that means good or normal also.
